More attractive structure and appearance,
Each valve come with manually hand lever extension.
2. Body: Ductile cast iron is heavy duty, more strength and
Abrasive resistance. Virtually dovetail groove body improve
Pressure resistance under vacuum pressure and prevent shivelled.
3. Labyrinth-type design, Labyrinth-like sealing
Maximum surface pressure between the body halves, leakage
Is highly improbable thanks to the labyrinth-type design.
4. Optional (antistatic) lining PFA or FEP particulary highly
Permeation-resistant, advanced Germany technology
Process by using Vertical injection molding machine,
While cooling and add lining materials at same time,
Which ensure density and uniform liner.
5. Standard one-piece ball/stem unit avoids weak spot ball
To stem, blowout-proof design. Fast replacement of ball/stem unit
Only if it broken. One-piece ball/stem with 3.5mm lining and
Stainless steel core.
6. Optional extra 5mm wall thickness PFA/FEP lining for high
Permeation resistance, corrosion resistance and vacuum-proof anchoring.
7. Bellows-type PTFE packing with stainless steel gland,
Better resistance to abrasion and stop any gas leakage.
8. The active stainless steel packing gland follower and spring gland follower
Can be self-adjusting.
9. Galvanized SS304 material parts are resistance corrosion and long life use
